Im a cosmetology student, and im working with a mannequin who supposedly has 100% human hair. The goal is to lift her to a level 9 so i can color her a bright green. Unfortunately, i can't seem to take her up any higher than a 7. I used Basic White lightener (the only one we're allowed to use for class) and 40 volume developer for 45 minutes. Rinsed her out and was at about a level 6.5. I tried again with the same lightener and timing, but i used 30 volume. Almost no change when she was clean and dry. Im not sure how to get her any higher without completely killing her hair. Any ideas?
maniquen hair is human hair, its also typically been treated with tons of hygene processes and 98 percent of the time it is dyed the non descript brown they all seem to be, i tried color remover on one in school and got orange hair from it, so likely its real hair but dyed
